The reliability of the human operator is an essential indicator of the safe operation of nuclear power plants. Mistakes can be made during performance checks, maintenance, at the stage of accident management, etc. A number of different factors affect the stability of a nuclear power plant: level of organization of the project, quality of equipment in operation, selection and training of competent personnel, maintaining the qualifications of NPP workers, and etc. In the “man-machine” system, the reliability of the technical component is calculated by known methods and in accordance with established reliability standards. However, the “human” component cannot be technically and accurately determined, therefore, it is necessary to undertake systematic efforts to increase and subsequently maintain the achieved level of reliability of this component. The contribution of the human factor to emergencies at technosphere facilities is significant: 70% of air crashes, 50% of disasters in the fleet occur precisely due to incorrect actions (low reliability) of personnel. According to statistics, the main causes of accidents are improper actions (low reliability) of personnel (60-70%), technical reasons (20-30%), adverse effects of external factors, etc. |
